Nope, only thing changed in latest nightly is improvements to the rounded template plugin to more properly act like an override/extension of the default template removing duplicate code. Beyond that there was nothing else changed in latest nightly. I have also confirmed taxes are outputting fine, see below screenshot. Does your tax rule have "Start date of validity of this tax" and "End date of validity of this tax" parameters supplied? If not please try selecting a date for both and see if issue persists.
